Yes but my P67 board use exactly the same ITE PCI bridge like this H97 so it cannot be a culprit. Looking at bare diagram dosn't show much as (d)evil is hidden in details that are not much published, one would need read full datasheet carefully...

Just a quick note, 6x chipsets (including my P67) are single-chip solution (PCH) - no more ICH10 used so it is not the mandatory condition for working DSDMA. But of course newer PCH chipsets might removed some internal legacy circuitry (as intel did e.g. for SATA-IDE emulation) that is crucial for …

Hi, I just got a Gigabyte GA-H97-HD3 rev. 1.1 mobo for 4./5. gen core with H97 PCH chipset & the same well known PCIE2PCI bridge IT8892E and performed a test with YMF744 PCI. I disabled all features that may interfere with DOS like USB legacy support and left only legacy boot, no UEFI etc. Yamaha …

No. It's the same. Interesting, I have found a JEDEC spec doc. where is drawing of 5V and 3V3 72p SIMMs and specially mentioned about a different keying! But there are also SIMM that use 3v3 memory chips and also includes LDO and maybe some level shifters that are mechanically compatible with 5V …

Does your BIOS have some option like memory remapping? If yes, try to change it when use 4GB or more. It may affect MTRR settings and performance. also you can try my latest mtrrlfbe with debug option to see if there is some difference in MTRR setting with 3GB and 4GB (under DOS).

I think R.L. memory patch should have nothing to do with performance issues and he wrote that he didn't use it anyway... I would try some nVidia VGA like GF6xxx or 7xxx on both MBs if perf. diff. would change...

In this article http://wp.xin.at/archives/5616 he also tried 3840x1600 but noted that "For a 4K/UHD monitor, 3840×2160@30Hz might work" that seems to me logical if you fit into HBR1 limit, of course there may be another obstacle preventing select this resolution but HBR1 bandwidth seems to be …

I read that nvidia drivers are crippled to support only HBR1 mode on DP output (while GPU itself support HBR2 but it works only in Win7+ …

Just use debug with command u dc00:0 to see if ROM is really there - it must start with bytes 55 AA then disassemble again u dc00:3 and you should see some JMP instruction that points to entry point of BIOS init code and u dc00:9 should show JMP to diag code, if the offset is correct...

Aha, OK thanks for info. Just to be clear what you mean by "pass through" - the VGA signal is only digitized and passed out pixel by pixel without any further transformations and processing so no delay introduced... 1600x1200 is good enoug but for my purpose OSSC is quite expansive and I don't …

Common LCD panels have OSD option to scale image to whole screen or keep 1:1. I don't know about this, I have no longer the LCD panel so I cannot test it now. BTW how about HDMI lines AC coupling?

The latency - maybe... It may help to set 1:1 on side of RTD or target monitor Bit depth - yes, probably BenQ panel was 6bpp, I don't know where the dithering is done if in RTD or LCD panel itself. But the chip could be reprogrammed to TrueColor output. This would be next step after making LVDS2HDMI …
